Figzffis a detail View of a part of the ice-bunker, and Figs. 4 and 5 are detail sectional views showing modified forms of the refrigerator or coolingin the double form this rooin.

This invention has relation io cold-storage' and refrigerating rooms of all kinds, and particularly such as are used by butchers or for the storage of butter, eggs, fruit, dac., the ob ject being to provide for a more equal temperature throughout the room, and especially at the upper portion thereof, and also to provide forabetter air circulation therein.

Vitli these objects in View the inventionA consists inthe novel construction and combination of parts, all as hereinafter described, and pointed out in the appended claim.

Referring to the accompanying. drawings, the letter A designates the outer Wall of the cold-storage or refrigerating apa1tment,which may be of the single form shown in Fig. l or of the double forni shown in Fig. 2. In the single form it has a portion B at one end which projects considerably above its top and is prof/died with a removable cover B', while extension is at the center. Extending from near the oorof the provision-chamber, from Which'it is supported by side legs thereof, uio within and near the top of the portion or extension B is an icefbunker C', open at the to entirely closed on all four sides, and provi 4ed with-a slotted bottom. Underneath this slotted betteln is? an elevated drip-pan D, secured 'fte said i o Ffvvnl-'r no o ro wie;

By means of .the said extension B, Ii provide for a considerablev body of ice above the top oi the room. Furthermore, l the censtrnctionof the ice-bunker causesa lively circulation .oil air. Forming as it does a laterally-closed line, the chilled air rapidly descends therethrough and escapes into the lower 'portion of the roem, displacing the air previously there and causing agapid circu'- y lation through the bunker, which results in iaintaining a nearly equal temperature throughout the room.

The contracted extension above the top of the provision-chamber concentratesthe hot air closely around and over the top of the icebnnker. This feature, in connection with the bunker constructed as described, facilitates rapid circulation of air, which can enter only at the top of the bunker, must pass through the entire depth thereof, and can escape only at the bottom of' the refrigerator and at its lowest temperature.

lt will be observed that my bunker, includn ing the drip-pan, is structurally independent of the refrigerator-body and that it may be readily entirely removed therefrom, leaving the refrigerator-body entirely free of any ledges or obstructions, whereby cleaning is facilitated.

Figs-4 and 5 of the drawings illustrate a reo - form of my inyention in which the contracted .jo A

extension vB is provided with a downwardl'y-y sloping side wall orwalls, wherebyany stag- A nation of the air circulation is prevented, the

warmer air passing Afreely np said sloping Walle to and over the ice-bunker.

I ar'rr aware that heretofore refrigerators have been patented disclosing the upwardlysloping Walls at the top thereof tofacilitate the rise of the warmer air toward the ice- I lo bunker and disclosing an extension of thetop of the refrigerator abovethe body thereof,into

` which projects an ice-bunker to eiecta downward draft of air throughthe-iceibunker from the top thereof and escaping at the bottom only thereof and of the refrigerator; vbut I aml not aware that heretofore these two features liave been combined, which eombinationre- :suits in a refrigerator in which the circulation of air will be niuch incre rapid than in either of the above-cited precedents, such rapid circulation of ail-.bein g the greatest desideratum in a refrigerator vand more important than even a low temperature, as it effects an evaporation of all moistureand keeps the refrigerator dry, it being well known that dry air is a great preservative, and such combination avoiding any necessity for partitions in the refrigerator, thus leavin-g more room for the storing of provisions. It will be noted that the drip-pan D, beinginclined downwardly to` ward the air-escape openings in the bottom of the refrigerator, will l deiiect the cold air falle' cliente ing in the ice-bunker outwardly through said escape-openings.

v Having thusjdescribedmy invention, what 3 I claim as new, and desire to secure by Letters Patent, is-

In a refrigerating or cold-storage room, for more rapid circulation of the air therein, dre.,

the provision-chamber having the contracted '4o' er;

extension of its top portion, said extension having an upwardly-sloping side Wall or Walls;

and the ice-bunker extending `from the bottom of said chamber, and projecting up within and near the top of said extension, said bunker 45 beingentirely open at the top,being entirely closed upon all sides thereof, and having airescape openings at the bottom, which bottom is formed bya drip-pan inclined downwardly toward said airfescape openings, whereby the 5a air is caused to pass freely up said sloping l, v A

side walls to and over the ice-bunker, down through the entire de th of said bunkerin immediate contact Wit Athe ice therein, and

deiiected by said inclined drip-pan to escape 55 at the bottom only of said bunker and refrigerator, substantially as specified.

.In testimony whereof I affix my Signat ure in presence of two witnesses.
